Looking north from Wildcat Mtn. Bob Raynolds (Denver Museum of Nature and Science) discusses how the Arapahoe conglomerate marks the start of the Laramide Orogeny in the Denver Basin. The Laramide Orogeny raised up the Rocky Mountains starting about 75 million years ago. Bob Raynolds was the Colorado Scientific Society President in 2018 and continues to be an active member.

Why Donate to the Colorado Scientific Society?

We use donations to supplement funds from membership dues to fund our meetings, field trips, and the CSS grants that help earth sciences students with their  research projects every year.

Colorado Scientific Society Meetings

We hold monthly meetings from September through May. (Many of our members do field research during the summer.)

Meeting presentations include: Geology, Paleontology (e.g. dinosaurs), Space Science (e.g. evolution of the solar system and Mars once had rivers and lakes), Ecology, and more.

Colorado Scientific Society Field Trips

We usually have about two one or more day field trips each year. We also have a few shorter half day trips called “No Moss” gatherings, as in “a rolling stone gathers no moss”.

Examining the Fountain Formation at Red Rocks on March 30, 2024. It consists sandstones and conglomerates interbedded with dark maroon mudstones deposited in alluvial fans along the the east side of the Ancestral Front Range about 300 million years ago. This was a No Moss Gathering.

Our field trips are open to the public and are often free. Look at our Home and Upcoming Field Trips pages to see coming field trips.

Student Research Grants

We make over $10,000 in  grants to assist students in their earth sciences research every year. We make grants to multiple students to help offset their research expenses, as opposed to a larger grant to a single student.
See the Colorado Scientific Society – Student Research Grants page for details about our student research grants.

The income from our Memorial Funds is used for our Student Research Grants each year to students in the Earth Sciences throughout the nation.
Ogden Tweto worked for the U. S. Geological Survey with distinction, compiled the Geological map of Colorado, and was CSS President in 1952.
Stephen S. Oriel worked for the U.S. Geological Survey concentrating on mapping the geology of the Idaho—Wyoming thrust belt. He was CSS President in 1971.
Edwin B. Eckel worked for the U.S. Geological Survey, especially interested in Engineering Geology. He headed the Geological Society of America and was CSS President 1950-1951.
Bill Pierce worked for the U.S. Geological Survey, with a special interest in the Heart Mountain fault, where blocks of Paleozoic limestone about half a mile thick slid rapidly over twenty five miles into the Big Horn Basin during Eocene time.
George Snyder had a 42-year career with the U.S. Geological Survey focused on Rocky Mountains Precambrian igneous and metamorphic geology and basement tectonics. He was CSS President in 1977.
During Bruce Bryant's career with the U.S. Geological Survey he became an authority on the Geology of Colorado. He was loved by all. Bruce was CSS President in 1985.
The Charles Pillmore Fund supports student participation on CSS field trips. Chuck was CSS President in 1983-1984 and wrote the draft guidelines for the Ogden Tweto Memorial Fund. He worked for the U.S. Geological Survey and discovered the world’s only undisputed fossilized footprint of a Tyrannosaurus rex.
